    Battery for Dell Laptop M5Y0X

    This battery was an exact match for my laptop, It allows for 4 hours of service on a full charge. The battery worked right out of the package. The battery has taken a full charge and seems to function perfectly. Discount Electronics shipped the item in a timely manner. I wouldn't hesitate to deal with them again or refer them.

    Was charged at 70% when installed. Charged up to 100% as expected. So far all is good. I expect to be ordering a second battery for my other Notebook.

    I tried to buy a battery from a competitor I had previously done business with. After over two months they refunded my money. My IT guy suggested Discount Electronics. Within a week I had my battery. I highly recommend this company.
